Setting up the Vertical Pod Autoscaler

3 min read

To be able take advantage of using a Cluster Autoscaler (same applies to AWS Karpenter) we need make sure we properly set the resources any scheduled Pod is requesting to Kubernetes:

• If we are requesting too much resources, we will be wasting resources
• If we are requesting too few, the application might end up on a node where it needs to constantly share resources with other Pods

When we are not use the resources a given Pod or container is going to use, we can use the Vertical Pod Autoscaler to help us define them
